cadmovie1027 – Introduction to BIM – Part 7

Like walls, slabs can have components, so you can make slabs and ceilings that have several components. The slabs can link to walls and slab components can link to the wall components. So it is really important that you create your walls and slabs in relation to each other.

  1. I followed this example through the first time in setting up a BIM project, but the inability to have the floors move with adjusting the story height made me wonder if there was a different approach to this.

    I set up the complex slab similar to the example in this video starting around the 4:35 mark. Instead of creating a ceiling with structural members in the Floor-1 level, I chose to create the complex slab as a floor in the Floor-2 level.

    The datum for the slab I created is the top of the “Flooring” component, instead of the top of the lining component in the video.

    Under Insertion Options, I set the Datum LayerZref to Finish Floor, and Datum offset from Layer Z to 0

    Save preferences as a slab style and click ok

    In an isometric view, I make sure I am have layer Floor-2 active, and have Layer options set to “Show/Snap/Modify Others”

    With the slab tool active, I select the bounding walls on Floor-1, doing so will create the complex slab on Floor-2 but will make sure the walls below it on Floor-1 terminate below the newly placed slab. Jonathan suggested I try this, and it worked. (Selecting the walls on Floor-2 will not allow the walls on Floor-1 to terminate below the slab)

    I repeat the process for the slab between Floor-2 and Floor-3. Layer Floor-3 is active and select the walls on Floor-2 to create the bounding walls for the slab.

    Now when I change Story heights, these floor slabs adjust as well.
